My lexus dealer gave me an amazing trade in value for my moms lx470 back in 2007, when we ordered the new '08 lx570.
We ordered the 570 in august and it wasnt going to arrive until christmas time, which got delayed to february!
However funny enough they sold the old lx470 just a few weeks before we picked our new lx570 in feb, could have just left it with us in the meanwhile
